Owners of electric scooters know the plight of the urban commuter: what to do when you arrive at your destination, only to find that you need to charge up? You can either lug it up the stairs, or upgrade to the UItra Motor A2B Excel Electric Scooter ($TBA). This lightweight electric scooter packs Intelligent Dual Electric Power (iDEP) that lets you take the battery with you when you park, making the scooter immobile while saving you the hassle of schlepping the whole damn thing inside.
